Pune-based startup Druva, which sells enterprise backup software, has just closed a second round of funding worth $10 million from Nexus Venture Partners, reports Economic Times.

In April 2010, Druva had raised $5 million from Sequoia and the Indian Angel Network. At that time, these are the reasons we gave for why we liked Druva:

• Druva is a purely homegrown startup. This is not a company started by someone in the US setting up a development center in India.
• Druva is a product startup. It is not a services company. Hence, it has a potential for exponential growth and returns.
• Druva is not done by serial entrepreneurs. The co-founders are all first-time entrepreneurs who quit their big-company jobs to start Druva. This should give hope to all the first-time entrepreneurs in Pune.

Druva has been one of PuneTech’s favorite startups and we have covered it extensively in the past, so, frankly, there isn’t much new that we’ll be able to say about it. Instead, we’ll simply point readers to the older articles:

• “World-class software products can come out of India” – Interview with Jaspreet Singh, CEO of Druva
• Druva: From proto.in presenter to proto.in sponsor in 18 months
• Understanding Data De-duplication – an article about an underlying technology that gives Druva an edge over its competitors
• Technology Overview – Druva Continuous Data Protection – An article about Continuous Data Protection, the first product that Druva came out with. As far as we understand, Druva is no longer selling this product. This is an interesting lesson on how software startups have to ‘pivot’ and change their product line in response to market demands, and how things can go in a completely different direction than what founders originally envisaged
• Understanding RTO and RPO in backups – A simple tech overview of the important parameters on which a backup solution should be evaluated.

We also want to point out that Druva is one of the sponsors of PyCon – the International Python Conference that’s happening in Pune next month.

We wish Druva luck, and although getting another round of VC funding is not as good an indicator of success as an IPO or an acquisition, we would still like to repeat what we said in April 2010:

• We now have in our midst a startup success story that will hopefully inspire a 100 new software product startups in Pune.
